- We use data from a survey of 2439 farmers in 5 countries around the Baltic Sea (Denmark, Estonia, Finland, Poland and Sweden) to investigate their preferences for adopting agricultural practices aimed at reducing nutrient leaching and greenhouse gas emissions. The measures considered are set-aside, catch crops and reduced fertilization. Contracts vary with respect to the area enrolled, contract length, possibility of premature termination, availability of professional advice and compensation. We quantitatively describe farmers’ preferences in terms of their willingness-to-accept compensation for specific attributes of these contracts, if implemented. The results vary substantially between farm types (farmers’ characteristics) and between the 5 countries, and support differentiation of contract obligations and payments to improve the uptake of AgriEnvironmental Schemes. The results can be readily used to improve the design of country-specific nutrient reduction policies, in accordance with the next Common Agricultural Policy.

Drivers of Farmers' Investments in Nutrient Abatement Technologies in Five Baltic Sea Countries
- 2019

- Adoption of new manure and fertiliser technology is considered an effective tool to reduce diffuse nutrient pollution from agriculture, and policy instruments to encourage technology uptake are therefore widespread. But policy makers need to understand farmers' reasons for adoption of such technologies to design policies that actually work. Using data from a survey with responses from 2439 farmers in five countries around the Baltic Sea, we identify the drivers of technology adoption for three different abatement technologies: manure spreading equipment, slurry tanks, and precision technology for fertiliser application. We compare drivers for technology investments across technologies with a particular focus on the role of the scale of farm operations, neighbour relations, environmental concerns and innovation readiness. The results show that the scale of farm operation is important for the uptake of all three technologies, while we find no evidence that neighbour relations are important for technology investments. Environmental concerns for soil quality and other on-farm environmental qualities do drive investment; however, the impact of environmental concerns differs across technologies. Innovation readiness is a driver of investments in relation to some technologies, suggesting that the novelty or sophistication of the technology matters to the investing farmers.

Forskningsöversikt (refereegranskat)abstract
- Vegetated coastal and marine habitats in the Nordic region include salt marshes, eelgrass meadows and, in particular, brown macroalgae (kelp forests and rockweed beds). Such habitats contribute to storage of organic carbon (Blue Carbon – BC) and support coastal protection, biodiversity and water quality. Protection and restoration of these habitats therefore have the potential to deliver climate change mitigation and co-benefits. Here we present the existing knowledge on Nordic BC habitats in terms of habitat area, C-stocks and sequestration rates, co-benefits, policies and management status to inspire a coherent Nordic BC roadmap. The area extent of BC habitats in the region is incompletely assessed, but available information sums up to 1,440 km2 salt marshes, 1,861 (potentially 2,735) km2 seagrass meadows, and 16,532 km2 (potentially 130,735 km2, including coarse Greenland estimates) brown macroalgae, yielding a total of 19,833 (potentially 134,910) km2. Saltmarshes and seagrass meadows have experienced major declines over the past century, while macroalgal trends are more diverse. Based on limited salt marsh data, sediment C-stocks average 3,311 g Corg m-2 (top 40-100 cm) and sequestration rates average 142 g Corg m-2 yr-1. Eelgrass C-stocks average 2,414 g Corg m-2 (top 25 cm) and initial data for sequestration rates range 5-33 g Corg m-2, quantified for one Greenland site and one short term restoration. For Nordic brown macroalgae, peer-reviewed estimates of sediment C-stock and sequestration are lacking. Overall, the review reveals substantial Nordic BC-stocks, but highlights that evidence is still insufficient to provide a robust estimate of all Nordic BC-stocks and sequestration rates. Needed are better quantification of habitat area, C-stocks and fluxes, particularly for macroalgae, as well as identification of target areas for BC management. The review also points to directives and regulations protecting Nordic marine vegetation, and local restoration initiatives with potential to increase C-sequestration but underlines that increased coordination at national and Nordic scales and across sectors is needed. We propose a Nordic BC roadmap for science and management to maximize the potential of BC habitats to mitigate climate change and support coastal protection, biodiversity and additional ecosystem functions.
